6N137M-V

Overview

The Everlight 6N137M-V is a high-speed logic output optoisolator featuring an 8-DIP package. It supports a data rate of 10 Mbps with propagation delays of 75 ns maximum for both low-to-high and high-to-low transitions. The device provides 5000 Vrms isolation voltage and a common-mode transient immunity of 5 kV/µs. It utilizes a DC input type with an open collector output capable of 50 mA per channel. Operating temperatures range from -40°C to +85°C, ensuring reliable performance in demanding electronic applications.

Feature Summary

• High-speed signal transmission capability up to 10 Mbps
• Robust electrical isolation with 5000 Vrms rating
• High common-mode transient immunity of 5 kV/µs
• Logic gate output configuration for direct digital interfacing

Applications

• High-speed data communication interfaces
• Industrial control systems requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'V' against the manufacturer's current datasheet to confirm packaging details and compliance status. Ensure the selected variant matches the required insulation voltage and operating temperature range for the target application environment. Cross-reference the pinout configuration with existing PCB layouts to prevent installation errors during integration.

Selection Notes

Select this component when high-speed digital isolation is required between circuit sections. The open collector output necessitates an external pull-up resistor for proper logic level generation. Consider the 75 ns propagation delay limits for timing-critical designs. Verify that the 50 mA output current capacity meets the load requirements of the receiving logic gate or microcontroller input.

Part Context

The 6N137M-V belongs to the 6N137 series of high-speed optocouplers manufactured by Everlight Electronics. This series is designed for applications demanding fast signal transfer and strong noise immunity. The device integrates an AlGaAs infrared LED emitter coupled to a silicon photodetector with integrated output driver circuitry, providing a compact solution for signal isolation.

Replacement Considerations

Direct substitutes include the 6N137S(TA) for surface mount applications and the standard 6N137M for through-hole mounting. Verify that alternative parts maintain identical 10 Mbps speed, 5000 Vrms isolation, and open collector output characteristics to ensure functional compatibility without redesigning the surrounding circuitry.
